SIDE-STRAP BUCKLE.

Patented Jan. 26, 1915.

[0 all whom it may concern:

Be it known that I, EMIL HARTMANN, a citizen of the United States,residing at Baltimore, in the State of Maryland, have invented a certainnew and useful Improvement in Side-Strap Buckles, of which the followingis a full, clear, and exact descrip tion.

In the use of buckles on side straps on knee pants or knickerbockers andsimilar articles, where the buckle is permanently attached to thearticle, and where the engaged strap has to be buckled and unbuckledfrequently, the strap is quickly mutilated or disfigured and rendereduseless by such buckling and unbuckling. Attempts have been made toobviate this diificulty by providing the buckle with other means thantongues or prongs for use as the engaging element; but buckles providedwith prongs or teeth for engaging the strap afford so much greatersecurity that they are more generally used than the other kinds offasteners. Prior to the present invention also, these side strap buckleswith prongs or teeth have been made with hooks to engage eyelets orsimilar openings in the article to which they are applied, so that thebuckle may be adjusted and secured in proper place on the strap and theparts fastened and unfastened without disconnecting the strap from thebuckle teeth. The present invention relates to this last mentioned classof side strap buckles.

The invention consists of a buckle, of the side strap type mentioned, inwhich a notched cross-bar is used in connection with a hook orequivalent head which may be engaged by the notched cross-bar to eifectthe fastening of the article and from which head the buckle may bereadily disengaged to permit the unfastening of the article withoutaltering the adjustment of the strap and buckle with relation one to theother, as I will proceed now to explain and finally claim.

In the accompanying drawings illustrating the invention, in the severalfigures of which like parts are similarly designated, Figure 1 is aperspective view of a portion of the lower end of one leg of a pair ofknee pants or knickerbockers with the placket unbuckled and open and thestrap and buckle turned back. Fig. 2 is a top plan view, and Fig. 3 is abottom plan view of the buckle detached. Fig. 1 is a cross section takenin the plane of line A B, Fig. 2, and looking in the direction of thearrows.

The drawings show the parts enlarged, although the buckles may be madein any required size.

Describing the invention as used to fasten and unfasten the placket of apants leg but without thereby limiting its applicability, it is to benoted that ordinarily a band 1 is placed at the bottom of the leg, andthis band is extended at one side to form the strap 2. On this strap isplaced a buckle 3 at the proper position to permit fitting of thetrousers about the leg of the wearer. On one of the end-bars i of thisbuckle are made the teeth or prongs 5, adapted to en gage the strap 2 tofix the adjustment of the buckle on the strap. Between the end-bar atand the end-bar 6 and extending integrally from the side-bars 7 is thecross-bar 8, preferably depressed below the level of the face of thebuckle, and this cross-bar is provided with a transversely arrangednotch 9 which is adapted to engage a head 10 on the opposite side of theband 1 to fasten the placket or opening in the bottom of the trousersleg. This head 10 may be, as herein shown, a hook, resembling in generalconstruction the ordinary lacing-hook commonly used on shoes, and soplaced that the notched crossbar may be engaged therewith and disengagedtherefrom readily in order to effect the closing and opening of theplacket.

In order to facilitate the finding of the hook, leading edges 11 of thenotch may be bent down slightly from the plane of the cross-barrearwardly, as shown in Fig. 1-, and this bending down of these edgestogether with the depression of the crossbar, will aid in increasing thefrictional engagement of the crossbar with the hook and so insure theretention of the fastening against accidental displacement in the move"ments of the wearer. The invention, however, is not limited to a bucklehaving the edges of the notched cross-bar deflected, as just described.

While the end-bar and its teeth 5 positively engage the strap, thefixing of the engagement may be insured by passing the free end of thestrap over the cross-bar and through the opening 12 between it and theend-bar 6 and underneath the said end-bar 6, as indicated in Fig. 1.

By the construction described, the buckle may be economically producedand subject edto the various manufacturing processes necessary to finishit, Without liability of injury to any of its parts, larly true ascompared with prior constructions Where a hook was formed on the buckleto engage an eye or an eyelet to effect the fastening of the article.

What claim is 1. A buckle, provided with means for holding a strap inadjusted position, and a depressed cross-bar, said depressed cross-barprovided With a notch arranged transversely thereof and adapted toengage a complemental fastening member on the part to be buckled.

2. A. buckle, provided With sidebars and end-bars, one of which latteris provided with means for holding a strap in adjusted position, and adepressed cross-bar provided with a notch arranged transversely thereofto engage a complemental member on the part to be buckled.

3. A buckle, comprising side-bars and end-bars, one of said end-barsbeing pro and this is particuend-bars, one

vided with teeth to engage a strap so that the buckle may be adjustedthereon in any desired position, and a depressed cross-bar provided Witha notch arranged trans versely thereof the leading edges of which aredepressed from the plane of said crossbar, said notch being adapted toengage a complemental member on the part to be buckled. i

4:. A buckle, comprising side-bars and of said end-bars being providedWith teeth to engage a strap so that the bucklemay be adjusted thereonin any desired position, and a depressed cross-bar provided With a notcharranged transversely thereof and with its opening adjacent the toothedend-bar and adapted to engagea complemental member on the part to bebuckled. j g

In testimony whereof I. have hereunto set my hand this 28th day of AprilA. 1914c.
